Episode complete credited cast:


Penny and Leonard are still at the stage of their "post-coitus" relationship where they feel awkward doing friend type things together. Regardless, when the guys experiment with bouncing lasers off the moon, Leonard decides to invite Penny to watch. With her is her latest date, Zack, a less than bright guy. This encounter with Leonard and Zack together demonstrates to Penny that she can't go back to dating the type of guys she used to date: good looking but dumb. In a drunken stupor later, Penny takes some action to reclaim what she's missed no longer dating Leonard. Leonard in turn, takes a cue from Penny's actions. Meanwhile, Howard and Raj believe the answer to Leonard's Penny conundrum is to find another woman for him. After Leonard rejects Howard's idea of using on-line matchmaking services, Raj thinks an interesting experiment would be to see if such a service would produce anyone for Sheldon. Howard and Raj's experiment does produce a match for Sheldon. Will he agree to meet ... Written by Huggo

Crazy Credits

CHUCK LORRE PRODUCTIONS, #288 Over the years, CBS executives have always been very generous when it comes to sharing their ideas as to how I might better do my job. I have never returned the favor regarding how they might run their network. Until now. Now I have a really good idea. Step One: Create an internal division with workers who do nothing but check out the claims of prospective advertisers. And I mean really check them out. If it's a car, have somebody drive it around to see if it accelerates into walls or slow-moving pedestrians for no particular reason. If it's beer, have someone drink it and report back if it gets them laid. If it's a pill, have someone take it for awhile, then wait to see if they grow a tail, get anal leakage, or commit suicide. Step Two: Quality control. All commercials must be aesthetically pleasing, seriously funny, poignant, or dramatic. Any commercials deemed loud, stupid and/or obnoxious are not aired. Period. No exceptions. Step Three: Tell the world that CBS only airs the coolest and most honest commercials. It's always Superbowl Sunday at CBS! Step Four: Watch the money roll in. A Final Thought: Don't worry about the initial loss of income created by dropping the dumb stuff (e.g. Cockney lizards who sell insurance). You'll more than make that money back by demanding that your high-quality advertisers cut you in for a piece of their action. You have, after all, earned it by giving them the CBS seal of approval. Another Final Thought: If you adopt my idea, my consulting fee is one million shares of CBS stock. Or better yet, one hundred shares of Apple stock. See more »

"The Lunar Excitation" is a fine third season ender of "The Big Bang Theory"
1 April 2011 | by (Baton Rouge, La.) – See all my reviews

In this season finale ep of "The Big Bang Theory" from the previous year: The guys are up on the roof to get objects on the moon reflected back on earth. Leonard decides to invite Penny up despite their recent breakup. Penny agrees to go-with her new beau who turns out to be really dumb with Sheldon first saying how perfect he is for Penny before saying she could do much better. Penny later confronts Leonard about how he ruined it for her since she now can't be satisfied with dumb hunks! Leonard decides to try to even the score by coming to Leslie Winkle (once again, Sara Gilbert) for another recreational sex. She slams the door in his face. Meanwhile, Raj and Howard have answered on online dating poll in Sheldon-speak to see if the latter gets a match. He does, which chagrins Sheldon to the bone but since Raj has hidden a smelly sock which Sheldon earlier freaked out about on the roof, Sheldon reluctantly goes...While I know about the rest of the ep from reading the synopsis on this site, that's all I got to see on the disc I recorded this on since the visuals became like pixilated during that time. But if what I read was as funny as what I think it would be if I was able to watch it, I think this was a great way to end this third season of this uniquely smartly written and popular series. So on that note, "The Lunar Excitation" seems like another excellently funny ep of "The Big Bang Theory".
